PROBLEM TO BE SOLVED: To provide a high frequency heating device capable of quickly switching high frequency heating coil and optionally adjusting the temperature distribution of an object to be heated, with long life and without taking time in adjustment works. SOLUTION: The high frequency heating device 1 uses a plurality of high-frequency heating coils 2, 3 to heat the object to be heated 100 with a high-frequency induction heating. The high-frequency heating device 1 comprises a plurality of high-frequency inverters 11, 21 supplying high-frequency heating power, output adjustment parts 14, 24 adjusting heating power to be supplied to the inverters 11, 21, and an inverter switching part 5 outputting signals for changing each heating power of the inverters 11, 21synchronizing with the switching of output signals of each output adjustment part 14, 24. The device optionally adjusts the temperature distribution of the part including a plurality of heated parts of the heated body 100. COPYRIGHT: (C)2004,JPO
